Participation PT FT
„ Why
„ Part
of larger analysis also looking at
work/notwork
work/notwork
– If the RN works, how much (PT or FT)
This work was supported by a grant from AHRQ R01
HS011320
Presented at AcademyHealth,
AcademyHealth, June 6, 2004
*University at Buffalo ** New York University
ƒ FT defined as >35 hrs per week for all jobs
Research questions
„ What
factors are associated with the work
decision (WK/NW) and amount of work
(FT/PT)?
„ Are the WK/NW and PT/FT decisions made
together or separately?
important:
– If only 10% of the PT RN population worked
FT, it would add 31,000 RNs to supply
Data sources
„ The
National Sample Survey of Registered
Nurses March 2000 (Spratley
(Spratley et al., 2001)
– County level data (some restrictions)
– Female RNs in 300 MSAs represented
„ MSA/County
level variables
– InterStudy Competitive Edge Part III Regional
Market Analysis (2002)
– Area Resource File (2002)
Sample
„ 35,358
registered nurses
„ Exclusions:
– Did not live or work in the USA
– Missing MSA codes for job and living location
– Did not work (or live) in an MSA
„ Analytic

„ Analytic

– Tested hypothesis that WKNW / FTPT
decisions are related

Interpretation of marginal effects
Probability of working or working FT
changes (+ or - )by amount of marginal
effect at mean of variable
Ex: The probability of a 25
- 30 yr old RN
working FT decreases by 0.12 compared to a
RN < 25

Significant Demographic variables in
PartPart-time / FullFull-time regression
„
Probability of FT decreases
– All age categories: Stronger effect for married, >60
– if any children < 6
ƒ Stronger for married ((-0.30 vs -0.17)
– Baccalaureate RN vs. AD
„
Probability of FT increases
– Minorities married, ME=0.16
– Total family income,
income, (non linear) NS for married
ƒ 0.30 to 0.19 for single
– Student status NS for married
Significant organizational variables in
PT/FT regression
„ Probability

– Satisfaction: small ME=- 0.01 married, ONLY
– Settings:
Settings: Educators, student health,
ambulatory care SIG vs. hospital RNs
„ Probability

– Function:
Function: Supervisors, teachers,
administrators vs. direct care RNs: ME=0.09

– Positions:
Positions: ALL other (NP, CNS, administrator,
etc) vs. staff RNs,

Implications
Conclusions
„
MSA level economic variables
– Influential on PT/FT decision, but not decision
WK/NW
„
Influence of demographic variables
„ What
to target single vs married RNs
organizations can change:
– Age, children, minority, income and student status
– Career orientation may influence PT/FT
– Education (BSN(BSN-married, Master’s single)
– Age related work conditions, esp after age 55
– Improve satisfaction
– Recruit minorities
ƒ more effect on FT work decision than WK
ƒ weak but negative = concern
„
„ Need
Organization variables
– satisfaction significant, neg,
neg, if married
– Hospital, direct care and staff RNs most likely to be
PT
– Functions and positions indicating career path more
likely to be sig
ƒ chicken or egg ? Develop career paths early
„ Work
work
decision different from how much to
Implications
„
Government policy
– Clarify education: rewards need to be clear
– Economic variables- need to understand
ƒ What can Govt manipulate?
ƒ May help in predicting regional variability in
shortages.
ƒ Job market or health of population?
– For ex: IOCIOC- perhaps hospitals are competing for nurses and
end up with more fullfull-time workers due to higher wages
